Python 包 mysqlclient 错误不允许在 MacOS 中安装包

Question

我有一台新的 Macbook Pro M3 Pro，我正在尝试在其上安装 Django 项目。

尝试安装 mysqlclient python 包时，

pip install -r requirements.txt

命令返回错误。错误如下：

Building wheel for mysqlclient (pyproject.toml) did not run successfully.

在要求中，包的版本是

mysqlclient==2.1.1

并且运行命令

pip install mysqlclient

会给出相同的错误。

我已经尝试过

brew install mysql-client pkg-config

命令，我还向

~/.zshrc

文件添加了变量：

MYSQLCLIENT_LDFLAGS="-L/opt/hombrew/opt/mysql-client/lib"
MYSQLCLIENT_CFLAGS="-I/opt/homebrew/opt/mysql-client/include"
PKG_CONFIG_PATH="/opt/homebrew/opt/mysql-client/lib/pkgconfig"

如这个问题所示：Cannot install mysqlclient on MacOS with no good result.

我还使用命令

brew install mysql

安装了mysql，结果相同。

我也使用通过brew安装的anaconda3，在项目中我将使用MAMP进行mysql数据库进程管理。

我找到了解决这个问题的方法。我以另一种方式定义了环境变量，以便可以正确构建包。变量是：

export MYSQLCLIENT_CFLAGS=`pkg-config mysqlclient --cflags`
export MYSQLCLIENT_LDFLAGS=`pkg-config mysqlclient --libs`

您需要安装 pkg-config。可以使用

brew install pkg-config

安装。

定义变量后，只需运行

pip install mysqlclient

，它应该可以正常工作。
